متن کاملDaily variations of indoor air-ion and radon concentrations.
Air-ions and radon are two atmospheric trace constituents which have two opposite effects on human health: the ions are beneficial, and radon gas is potentially lethal as it increases the risk of lung cancer. In the lower troposphere, radon is the most important generator of the air-ions. Ionization by cosmic rays and radioactive minerals is almost constant in daily cycles, and variation of air...
متن کاملDetermination of Polycyclic Aromatic Hydrocarbons in Ambient Urban Air
Polycyclic aromatic hydrocarbons (PAHS) have been determined in the atmosphere of Isfahan, Iran. Airborne particulate matter was sampled using a high-volume air sampler at roof-top level (~6m). Extraction of PAHS from airborne particulate matter has been performed using SFE system and the relationship between the extraction temperature and the recovery of PAHS</su...
متن کاملSpatial variability and trends in ambient air concentrations of metals in Cracow, Poland.
Even though the air quality has been improving since the beginning of the 1980s, Cracow still belongs to the most polluted cities in Poland. The air pollution originates mainly from industry, small-size emission sources and transport. Metals in ambient air have been monitored since 1992 by 4 stations located within the city. The aim of the study was to determine the city areas where the nationa...
متن کاملVariability of Metal Composition and Concentrations in Road Dust in the Urban Environment
Urban road dust comprises of a range of potentially toxic metal elements and plays a critical role in degrading urban receiving water quality. Hence, assessing the metal composition and concentration in urban road dust is a high priority. This study investigated the variability of metal composition and concentrations in road dust in 4 different urban land uses in Gold Coast, Australia. Samples ...
